Laravel 8 installation problem

[landg16]

Hi, I have a problem, when I try to install following package on Laravel 8 composer has conflicts. I've tried older versions of this package but still not success. Here are composer errors:

our requirements could not be resolved to an installable set of packages.

Problem 1

• laravel/passport[v8.0.0, ..., 8.x-dev, v9.0.0, ..., v9.2.2] require guzzlehttp/guzzle ^6.0 -> found guzzlehttp/guzzle[6.0.0, ..., 6.5.x-dev] but it conflicts with your root composer.json require (^7.0.1).
• laravel/passport 9.x-dev requires phpseclib/phpseclib ^2.0 -> found phpseclib/phpseclib[2.0.0, ..., 2.0.x-dev] but the package is fixed to 3.0.4 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
• laravel/passport[v9.3.0, ..., v9.3.1] require illuminate/auth ^6.0|^7.0 -> found illuminate/auth[v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev] but these were not loaded, likely because it conflicts with another require.
• laravel/passport[v9.3.2, ..., v9.4.0] require illuminate/auth ^6.18.31|^7.22.4 -> found illuminate/auth[v6.18.31, ..., 6.x-dev, v7.22.4, ..., 7.x-dev] but these were not loaded, likely because it conflicts with another require.
• coderello/laravel-passport-social-grant 3.0.0 requires laravel/passport ^8.0||^9.0 -> satisfiable by laravel/passport[v8.0.0, ..., 8.x-dev, v9.0.0, ..., 9.x-dev].
• Root composer.json requires coderello/laravel-passport-social-grant 3.0.0 -> satisfiable by coderello/laravel-passport-social-grant[3.0.0].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Okay, turned out I was not able to install passport also. I deleted composer.lock, reinstalled everything and works fine.
